From de58ac49a5d941a053008bf395c862efc34b5595 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 28 Feb 2022 13:48:39 +0100 Subject: [PATCH] armv8: psci: skip setup code if we are not EL3 If we are running in EL2 skip PSCI implementation setup. This avoids an exception if CONFIG_ARMV8_PSCI is set, but u-boot is started by TF-A.
